I found this recipe on http://www.epicurious.com. We use a lot of it, and it keeps a long time, so I quadruple the recipe when I make it. The quadruple amounts are in parentheses.
Worcestershire Sauce:
1/2 cup (2 cups) apple cider vinegar
2 Tblesps (1/2 cup) tamari soy sauce (San-J brand–this is just made with soy–no wheat)
2 Tblesps (1/2 cup) water
1 Tblesp (1/4 cup) molasses (or yacon syrup)
1/4 tsp (1 tsp) ground ginger
1/4 tsp (1 tsp) dry mustard
1/4 tsp (1 tsp) onion powder
1/4 tsp (1 tsp) garlic powder
1/8 tsp (1/2 tsp) cinnamon
1/8 tsp (1/2 tsp) pepper
Place all ingredients in a medium saucepan and stir thoroughly.
Bring to a boil, stirring constantly. Simmer 1 minute. Cool.
Store in the refrigerator.
Makes 3/4 cup (3 cups).
Shake well before using.
